APPARATUS FOR RElWl/ING SHEETS F GSS FROM ANilEllLihlG-OlllllS.

SPECHECATION forming part of Letters Patent No. 32%,E33, dated Augustl,1885.

g Application 'filed May lf3, 1885, (No model.) K l To all whom it mayconcern: Y Beit known that l, JOHN GASNER, a citizen of the UnitedStates, residing at Covington,

in the county of Tioga and State oi Pennsylvania, have invented certainnew and useful improvements in Apparatus for Removing Sheets of Glassfrom the ,annealing-Gwen;

` and I do hereby declare the following to be a i full, clear, andexact. description of theinvention, such as `will .enable others skilledin the art to which it appertains to make and use the same, referencebeing'had to the accompanyi thereof.` i

The object of this invention is to improve Aupon the devices heretoforeused for removing plate and sheet glass from'the annealingfurnaee. Indevices of this class now in use one set of bars has been constructed toreciprocate between the other, one setfbeing stationary-that is,as tomovement ina longitudinal direction--no meanshave been provided forpreventing the bars from getting 'oid' their -supporting-standards andyet leavinggthem free to expand and contractwithont straining orspringing the bars; and other defects have been discovered, all of whichl seek to overcome by the improvements now to be described. t

- The invention consists in certain'` novel de.- tails of construction,hereinafter more folly described, and thenspecically' pointed ont in theclaims.

Referring to the accompany drawings, Fignre lis avertical longitudinalsection of my improved device, showing also the annealingarch and aportion of the furnace.' Fig. 2 is a invention.

In the drawings, A represents a portion of the furnace .in which theplates of glass are heated and flattened, and A'is the annealing B B arethe side Walls of the anneaiinglarr h,

g drawings, which form a part" c are armsdesigned to support the bars C,6o i and lare similar arms designed to support 'the bars C. Each ofthese armsis bifurcated at-,each end, as shown, and, in the fork of thelower end is pivoted thecrank-arm b, `the opposite end of which issleeved on its'appro- 6,5 priate shaft a. These armsc c' are locatedupon opposite sides of their shaft, and consequently the cranliarms bofeach lset extend,-

iu opposite' directions.` The upper ends of these arms are connected tothe .nppershafts in a similar manner. lin thefupper ends of each ofthese arms c c' is -jonrnaledan antifriction roller, d, upon which restthe"v bars C C. Thesebars are preferablyT T-shapedin cross-section,althoug'hacruciform or tubular bar may be sometimes used. The base ofthis bar nests upon the roller d, `and in recesses' formed in the top ofthe arms d ofthe arms c c are jourualed the horizontal friction-rollersd?, beneath which ,the flange of the bars 8o- C G. proj nets, and thebars are thus vprevented from rising, and lyet are free to expand aetheybecome heated. The rollers d2 bear against' the sides of the verticalportion of the bars and assist them in their reciprocating movement.

The bars C C are arranged in two sets, and while these sets may becomposedof more or less bars II have found from'experience that four inone set and i've in the other is best 9o suited for the purpose, andhence have so shown them in the drawings. The bars of each set areconnected together at their outer ends by the crossbars e e', The uppershafts c: extend through the side Walls of theannealing-arch upon oneside thereof, and lpi-voted upon each of these shaft-extensions exceptthe outer one is a two-armed lever, D, each arm of which is providednear its puter end Witha pin, D. jj

Upon the projecting end of4 the outer shaft u pivoted the three-armedlever, Di, the short arms oi which are provided with pins similar-tothose on the levers D. Thelong arm I Oi 2 t'ceases of this lever yformsa means for operating the then takes hold:l of the cross-bar connectingthese bars and pulls vtoward him,which causes the ends to move,with thesheet of glass upon them,until the sheet of glass com es over the endslof the otherset of bars. 'The operator then moves the le'ver'D2 in theoppositedirec tion,so as to lower the bars on which the glass hadfrom-one set o f bars to the other, and' thel chamber until, asseen in nowrests, the Isame movement bf the'lever lraising the other set of bars,which, coming in contact with the glass, raises it on of the set beinglowere'd,and ,the glass is thus transferred from onesetof bars to theother.. Take off one sheet of glass, then lower the bars and push intothe furnace glass being placed on the.

upper bars,when the operation is-.repeated.

By the reciprocating motion 'of the bars,A

together 'with the raising and lowering of b oth sets of bars, al gentlechange of the sheets is glass mo'ves onward throu h the annealingsheets,E,ii1l the chamber, after which the operator, at each-reciprocal`movenient Iof thel bars, removes from the exit a sheet ofglass. i

This he repeats as long asthe furnace is in op eration.4 f j .1. Havingthus described my invention and set forth its-merits, what I claimas-new isy 1. In aldevice for the-purpose described, two sets oflongitudinally-reciprocating bars g.l 1, a series of,

loosely mounted upon oscillating arms, coin-V bined' with thefriction-rollers d and horizontal rollerszd2 (Il, as and for thepurposes set forth. .i

2. In al device for the purpose described,

kthe combination of the shafts a, vertical bi furcated arms c c', thecrank-arms b, sleeved on the shaft and its opposite end pivoted in thelower: forks of said arms, and the bars C C', loosely secured in theupper bifurcated ends of said arms, as andv for the purposes set forth;f

v3. In a device for the purpose described,

the vertical arms c o', carrying friction-rollers d and horizontalrollers d2 d", combined withthe barsC C', the flanges of which extendbeneath saidf rollers d (Il, as and forA the purposes set-forth.

4. The verticall arms c c', bifurcated, as shown, the frictionrollcrs d,journaled between the forks thereof, and the rollers i d, journaled inrecesses in said bifurcated arms, combined with the T-shaped bars,'thebase of which rests upon the rollers d, and the flange A vpassed beneaththe rollers d da, which bear against the' vertical portions of saidbars, as-

and for the purpose set forth.

5. The combination of the shafts a, vertical arms c c', the crank-armsb, connecting said arms upon opposite sides of said shafts, the

levers D D D D, upon projecting ends of said shafts, andtheconnecting-bars D D, joining saidslevers; 'as' andior thepnrposespemed:In testimony whereof I. affix my signature in presence of two witnesses.
